Police Search for Missing Plano Fitness Instructor

Police found her purse, cellphone and coffee cup inside the club, but she and her 2010 Toyota Rav 4 were missing. Investigators said signs of a struggle in the club indicated early on that Loper may have been a victim of foul play.

At about midnight Wednesday, Loper's abandoned SUV was found near Parker Road and the Dallas North Tollway. Investigators said evidence in the vehicle indicated that Loper had been abducted -- but they didn't specify what that evidence may be.

Loper, a single mother, has taught Pilates at the country club for the past 16 years.

”She never would not be here to see her son come home from school, never,” longtime friend Julie Mitchell said. “We’re just trying to stay focused on getting everything done that we can. We’re reaching out to as many people as we can and trying not to think about what could be happening to her."

Loper’s friends and family have gathered at her Frisco home, praying she'll come walking through the door.

“We need her," Mitchell said. "We need her to come home. Her boy needs her. Our world isn't the same without her."
